ocfs2: Remove the ast pointers from ocfs2_stack_plugins 

With the full ocfs2_locking_protocol hanging off of the
ocfs2_cluster_connection, ast wrappers can get the ast/bast pointers
there.  They don't need to get them from their plugin structure.

The user plugin still needs the maximum locking protocol version,
though.  This changes the plugin structure so that it only holds the max
version, not the entire ocfs2_locking_protocol pointer.
